Where are the sunroof drainage outlets located on the Skoda Superb?

The sunroof drainage holes are located at the front left and front right corners of the car's sunroof. Sunroof leakage: Check if the drainage outlets are blocked. Even when the sunroof is closed during rainy days, rainwater can seep into the car through the gaps around the sunroof. Modern vehicles are designed with water-resistant channels where rainwater flows along the guide channels through the front and rear drainage holes, passing through the A-pillar or C-pillar, and eventually draining out from the bottom of the car. Unless both left and right drainage holes are blocked simultaneously, water accumulation in the sunroof is generally unlikely. Solutions for sunroof leakage: The main cause of sunroof leakage is blockage of the car's sunroof drainage holes by leaves, dirt, or other debris. During vehicle use, it is important to regularly clear the drainage outlets located at the four corners of the sunroof and check if the connecting joints of the drainage hoses have become detached.
As a seasoned technician with over a decade of experience at a 4S dealership, let me explain the sunroof drainage ports on the Superb in detail. There are drainage ports at all four corners of the roof. The front two are located at the front end of the sunroof rails—just peel back the rubber seal to spot the small holes. The rear ones are hidden inside the C-pillar trim panels. Follow the A-pillar downward to behind the front wheel arches, and you'll feel the rubber tube ends on the inner side of the fender—that's where the water exits. This design tends to accumulate leaves and debris. Last summer, one owner ended up with a completely flooded floor. Here's a tip: Every quarter, use a syringe to inject water into the drainage ports and check if it flows out behind the wheels. If the flow is slow, clear it with a bicycle brake cable. Never use an iron wire—puncturing the tube would make things worse.
After owning the Superb for five years, I've cleaned the drainage outlets myself. The location is actually quite easy to find. Standing next to the car and bending down to look above the wheel, at the seam between the fender and the body, there are two flat rubber nozzles behind the front wheels—those are the drainage pipe outlets. The inlets near the sunroof are even simpler: open the sunroof and you'll see small holes at the four corners; shine a phone flashlight to spot them clearly. Last time after a heavy rain, I noticed water dripping in the passenger footwell and realized they were clogged. Using a drainage pipe cleaning rod bought online, I poked through and flushed out a pile of black sludge. I recommend cleaning them once each in spring and autumn—just remove the door frame rubber seals to access them. If the drainage pipes age and crack, the rubber nozzles will harden, in which case you'll need to replace the pipes.
